BLIND AND SHUTTER.

. the city of WVashington, in the District of CovIO lumbia, haveinventedcertain new and useful Improvements in Blinds and Shutters, ofwhich the following is a specification. I v

In making my improvements I have had mainly in view inside window blindsfor houses; but the invention is applicable to shutters, screens, 850.,for any use.

It has been my object to make a screen, blind, or the like which, whenopen or drawn up, will be put into small compass, something like aVenetian blind. This result I find I can attain by combining with'theblind or screen slats lazy-tongs, by which they are held and with whichthey move, whereby the slats will lie flat and close together when theblind is open, and will be drawn apart, and at the same time inclined orslanted, when the blind is closed or extended, the degree of inclinationof the slats, and consequently the extent of opening between the slatsfor the admission of light, being determined by the extent to which theblind is drawn out. It is this combination of blind or screen withlazy-ton gs, to which the slats are attached and with .which they move,that mainly characterizes my invention.

The nature of my invention and the manner in which the same is or maybecarried -into effect will be readily understood by reference to theaccompanying drawings, in which I have represented my improvements-intheir preferred form.

Figure 1 is a front 'view, partly in section, of a window-blind made inaccordance with my' invention. Fig. 2 is a side view of the same,showing the lazy-tongs arrangement.

Fig. 3 is a front viewof the same. Figs. 4, 5, 6, 7, and 8 are detailviews,which will be hereinafter .more fully described.

A are the slats, and a la are the two sets of metallic arms constitutingthe lazy -tongs. There are two lazy-tongs, one at each side of theblind. Arms a are firmly fixed to the ends of the slats A, so that thelatter in reality form partof the lazy-tongs. Indeed, arms a could bedispensed with, and the slats A and arms I) pivoted directly together.The arms a are preferred, because they serve to increase materiallythedurability of the blind, and to SPECIFICATION forming part of LettersPatent No. 287,712, dated October 30, 1883.

Application filed August 9,1883. (No model.)

.render less likely the splitting of the slats or the working loose ofthe pins.

The arms a are of metal, and can be madeas, for instance, bycasting-easily, quickly, and at small cost. Each consists of a plate orstrip of the size and shape of the end of the slat, provided on itsinner or-rear face with three spurs,-0, by which it is held firmly tothe slat,and on its outer face with two pivotpins, (1 (1, one at eachend, and a central pivot pintle or pin, e. The armis readily attachedand then hammering it up into place,with the effect of course of drivingthe holding-spurs 0 into the slat. metal, and preferably are cast, areprovided each with end holes, f, to fit on the end pivots, d d, of armsa, and with a central guide-pin, 9, made tubular, or provided with asocket, so as to fit upon the central pintle, e, of arms a.

To secure the parts together the slats A, provided at their ends witharms a, are laid fiat one upon the other. The other arms, I), are nowapplied to arms a, as indicated in the drawings, each arm I) beingfitted at one end upon the pivot-pin d of one slat and at the other'endupon the pivot-pin cl of the second slat above, and at the centerv uponthe pintle e of the intermediate slat, which pintle enters the socket inthe guide-pin g.

One way of applying the blindto a window is indicated in the drawings.In the sides of the window-frameB are formed vertical grooves h, of awidth equal to or a little exceeding that of the slats. These groovesare toreceive the ends of the blind, and to hide the lazy-tongsarrangement. Extending lengthwise and midway of each groove h is anarrow groove, '5, which is the guide-groove into which the centerguide-pins, enter. The top slat, A,'of the, blind necessarily can haveno vertical movement. It is therefore pivoted by its pin in holes orsockets in the window-frame, so that it can turn, but not move up ordown.

rail, A by eyes j, which encirclethe guide-pins yon the center pintlesof A Oross-rail A and is provided with a thumb or finger piece, A. Bytaking hold of the latter theblind can be raised or pulled down withouttrouble.

has also guide-pins, which move in grooves t,

to the slat by fitting it on the end of the latter The bottom slat, A isconnected to a crossa I11 order to facilitate the operation, and to holdthe blind in any position to which it may be moved, I employcounter-weights C, which run in boxes D in.the wimlow-frame, and areconnected to the blind by cords k, which pass up from thecounter-weights over pulleys Z, and thence down to the bottom rail, towhich they are fastened. The weight of the blind is thuscounterbalanced, so that the blind will remain in any position to whichit may be moved. \Vhen the blind is raised, the slats lie fiat andclosely packed together. IVhen it is fully drawn down, the slats areslanted to their full extent, and are closed against the admission oflight. In proportion to the extent to which the-blind is drawn down orextended the slats will be correspondingly drawn apart and slanted.

In some cases, particularly for windows of considerable length, I haveone blind at the top to draw down and another blind at the bottom todraw up, arranging them so that when extended, or nearly extended, theywill meet at about the longitudinal center of the window. They may beindependent of each other, if desired, and this generally will be thearrangement; but the two can readilybe so connected that a movement ofone in either direction will induce a corresponding movement of theother.

I have indicated what I now believe to be on the whole the best way ofcarrying my invention into practical effect but I desire it to beunderstood that I do not restrict myself to the mechanical devicesherein described, for the details of construction, without departurefrom my invention, can be varied in manyparticulars, depending upon theplace where the blind is to be used and the use to which it is to beput.

\Vhat I claim as new and of myown invention is 1. The combination, in-ablind or screen, of lazy-tongs, and slats connected thereto,substantially as hereinbefore described, so as to be integral with or tovirtually constitute-one limb of the lazy-tongs system, as set forth.

2. In a blind or screen, the combination, with slats, of connecting-armspivoted to said slats in the manner of lazy-tongs, and provided withcentral guide-pins adapted to move in guide grooves or ways when theblind is being extended or contracted, substantially as and for thepurposes hereinbefore set forth.

3. In a blind or screen, the combination, with the slats and thelazy-tongs connections for the same, of counter-weights connected to theouter or moving end of the blind, substantially as and for the purposeshereinbefore set forth.

4. The arm a I), made as hereinbefore de scribed, in combination withthe slats connected thereto, substantially in the manner and for thepurposes set forth.

5. The combination of the arms a I), the slats connected thereto, asherein described, and the blind or screen frame provided with guidegrooves or ways, to receive the central guide-pins of arms I),substantially as and for the purposes set forth.

6. The combination,with the blind or screen frame and guide grooves orways formed in the same, of the blind-slats, their lazy-tongsconnections, as described, and the hand or cross rail connected by eyes,hooks, or their equivalents to the moving end of the blind,substantially as and for the purposes hereinbefore set forth.

In testimony whereof I havehereunto set my hand this 28th day of July,'A. D. 1883.
